Sliding clasp fastener



1 Aug. 17,1937. P. HOSSMANN SLIDING CLASP FASTENER Filed July 10, 1955 Paul Hossm knn INVENTOR BY I 31 r ATTORNEY Patented Aug. 17, 1937 PATENT OFFICE 2,090,124 SLIDING CLASP FASTENER Paul Hossmann, Berne, Switzerland Application July 10, 1935, Serial No. 30,659

/ In Switzerland July 14, 1934 Sliders for fasteners of the sliding clasp type are already known, the upper slider shield of which can be turned upwards for the purpose of enabling the slider to be opened in the event of a hitch in the operation of the fastener. Thus for example in one of such sliders the upper slider shield is divided in the longitudinal direction, and one of these parts can be turned upwards. In other sliders which can be turned upwards, the upper slider shield is connected at the pulling end to the bottom shield, so that on turning upwards, the slider is completely opened, and is separated from the fastener. All these sliders comprise separate closing members or closing devices which normally have to keep the slider closed. This is however a drawback, for in such fasteners fitted to sports clothes, it is very frequently impossible 'to open the slider in case of necessity. Moreover, in sliders which can be turned completely upwards, the closing device is liable to open accidentally, and so the slider is lost.

The present invention. obviates these drawbacks, mainly by replacing the closing devices referred to above by a closing spring well known in itself. This is however only possible provided that care is taken at the same time to ensure that the upper slider shield cannot be turned upwards throughout the whole of-its length, as otherwise the closing members would lose their guidance. According to the invention the upper slider shield is therefore divided transversely a little above the straight part of the I slider guide, so that the part of the slider shield, which is situated above the rectilinear guide, can be turned upwards in opposition to the action of the closing spring.

This construction according to the invention ensures an entirely novel effect as compared with the well known hinged sliders. If for example the fastener is to be closed. and the slider in doing so strikes an obstacle, the movable part will be raised in opposition to the action of the closing spring, and the slider will slide over the obstacle and will then be able to bring into engagement the closing members situated behind it. The fastener will be therefore closed even if some of the members remain out of engagement. This is quite impossible in the case of the well known sliders. It will be clear that the fastener closed in this manner, can be opened again directly by moving the slider back, as also in this movement, the hinged part will simply slide over the obstacle. The sliding clasp fastener can he therefore operated even in dlflicult conditions, which undoubtedly constitutes a considerable advance on the known constructions.

One embodiment of the invention is illustratively exemplified in the accompanying drawing, in which:

. Fig. 1 is a plan view and Fig. 2 a side elevation of the improved slider. Referring now to the figures, I indicates the upper slider shield and 2 the bottom slider shield. The upper slider shield I is subdivided into two parts transversely along the line Ia, which passes above the straight part 3 of the slider guide and slightly below the slider wedge 4, one of said part, designated 5, can be turned against the action of a spring I about a hinge 6 arranged transversely of the slider shield l. The special advantage of this construction consists in the fact that when in closing or opening the fastener the slider strikes an obstacle, the part 8 will be automatically turned upwards, and the slider will be able to pass over the obstacle and to effect the closing or opening of the remaining part of the fastener. After the removal of the obstacle, the fastener can be operated again in a normal manner.

An ear 8 is provided on the hinged part 5 and a similar ear 9 on the other part of the slider shield i. The ear 8 can be used to turn up the part 5 by hand if desired. A pull is fixed to the ear 9 for the purpose of operating theslider.

The invention can also be applied to sliders without a wedge.

What I claim is:-

1. An improved slider cooperable with the interlocking fastener elements of a separable fastener, said slider comprising an upper slider shield and a bottom slider shield, both said shields directly engaging said fastener elements and having a straight part and a diverging part at least one of these shields being subdivided, a little above the straight part thereof, in the transverse direction into two parts, one of which, the part comprising the straight part, is swingably attached to the slider, a spring being provided and arranged so as to resist oscillations of said part.

2. An improved slider for fasteners of the sliding clasp type, comprising an upper slider shield and a bottom slider shield both said shields having a straight part and a diverging part, at
